So the Nokia 7 plus is supposed to have a Secondary telephoto lens for 2x optical zoom. But there is no way(not that I am aware of) in the Nokia camera app to use that lens.
There is a button for 2x zoom in the camera interface. But when you click that the secondary camera is not used. It is digitally zooms with the primary lens.
I was curious if the telephoto lens is actually being used or not, so i clicked different pictures with 1x and 2x zoom and when I compared the info of the pictures, both the 1x as well as 2x pictures were using the same 12.2MP/f1.8 lens.
This makes the secondary lens just a decoration if you can't use it. (unless for the portrait shots, which I don't think is very convenient, but that's another story).
Am I missing something here? Is there a way to use the optical zoom features or is Nokia missing so something.
